<a name="details" id="details"></a><h2 class="groupheader">Detailed Description</h2>
<p>ovis is a simplified rendering wrapper around <a href="https://www.ogre3d.org/">ogre3d</a>. The <a href="https://ogrecave.github.io/ogre/api/latest/_the-_core-_objects.html">Ogre terminology</a> is used in the API and <a href="https://ogrecave.github.io/ogre/api/latest/_scripts.html">Ogre Script</a> is assumed to be used for advanced customization.</p>
<p>Besides the API you see here, there are several environment variables that control the behavior of ovis. They are documented in <a class="el" href="../../d2/d17/group__ovis.html#gae540577f6f783d26c37319663c8245ad">createWindow</a>.</p>
<h2>Loading geometry</h2>
<p>You can create geometry <a class="el" href="../../d2/d17/group__ovis.html#ga5648ab6b81d2764eb1865ca55fe95e80">on the fly</a> or by loading Ogre <code>.mesh</code> files.</p>
<h3>Blender</h3>
<p>For converting/ creating geometry <a href="https://www.blender.org/">Blender</a> is recommended.</p><ul>
<li>Blender 2.7x is better tested, but Blender 2.8x should work too</li>
<li>install <a href="https://github.com/OGRECave/blender2ogre">blender2ogre</a> matching your Blender version</li>
<li>download the <a href="https://www.ogre3d.org/download/sdk/sdk-ogre">Ogre MSVC SDK</a> which contains <code>OgreXMLConverter.exe</code> (in <code>bin/</code>) and set the path in the blender2ogre settings</li>
<li>get <a href="https://github.com/OGRECave/ogre-meshviewer">ogre-meshviewer</a> to enable the preview function in blender2ogre as well as for verifying the exported files</li>
<li>in case the exported materials are not exactly how you want them, consult the <a href="https://ogrecave.github.io/ogre/api/latest/_material-_scripts.html">Ogre Manual</a></li>
</ul>
<h3>Assimp</h3>
<p>When using Ogre 1.12.9 or later, enabling the Assimp plugin allows to load arbitrary geometry. Simply pass <code>bunny.obj</code> instead of <code>bunny.mesh</code> as <code>meshname</code> in <a class="el" href="../../d5/d68/classcv_1_1ovis_1_1WindowScene.html#a08fdc90b961da70aaf58cad08a9e97d8">WindowScene::createEntity</a>.</p>
<p>You should still use ogre-meshviewer to verify that the geometry is converted correctly. </p>
